Are young children showing early signs of communication delay?

Use CSBS DP™, an efficient screener that measures 7 key language predictors

CSBS DP logoDerived from CSBS™ and compatible with most developmental curricula, the Communication and Symbolic Behavior Scales Developmental Profile™ (CSBS DP™) is the best and easiest way to pick up early delays in social communication, expressive speech/language, and symbolic functioning—often the first sign of a developmental delay or disability. Based on both parent report and face-to-face evaluation of the child, CSBS DP results provide a great starting point for planning IFSPs, identifying areas for further assessment, determining the efficacy of interventions, and documenting changes in a child’s behavior over time.

The CSBS DP Infant-Toddler Checklist, the first component of CSBS DP, made headlines in a widely publicized study reported in the April 2011 Journal of Pediatrics: When pediatricians used the checklist to screen children at 1-year well-baby check-ups, the tools showed great promise in detecting possible early signs of autism. Download the ITC for free and get the companion Easy-Score™ CD-ROM that makes scoring and interpreting results a snap.
